Geodesic Dome in Vancouver BC, at sundown - Telus World of Science.(known as "Science World" by most).

During Expo 86 it was known as Omnimax Theater, - it has the worlds largest omnimax screen, in the upper section, and the theater seats 400 people. We saw the shows inside there during Expo 86.

It was designed by Buckminster Fuller. The structure looks very pretty at nights, as it's covered with lights.
